A New York appellate court suspended Rudolph W. Giuliani’s law license on Thursday after a disciplinary panel found that he made “demonstrably false and misleading” statements about the 2020 election as Donald J. Trump’s personal attorney.

The court wrote in a 33-page decision that Mr. Giuliani’s conduct threatened “the public interest and warrants interim suspension from the practice of law.”

Mr. Giuliani helped lead Mr. Trump’s legal challenge to the election results, arguing without merit that the vote had been rife with fraud and that voting machines had been rigged.

“We conclude that there is uncontroverted evidence that respondent communicated demonstrably false and misleading statements to courts, lawmakers and the public at large in his capacity as lawyer for former President Donald J. Trump and the Trump campaign in connection with Trump’s failed effort at reelection in 2020,” the decision read.

Lying to courts is a big no-no for lawyers. It's actually one of the lawyering rules that you can't lie to the courts.

the other side prove every fact necessary to win.* Not so much "my client didn't do it" as it is "the State has not met its burden of proving that my client did it."
